Embedded contact type fan structure

The utility model relates to the technical field of vehicle-mounted host heat dissipation structures, in particular to an embedded contact type fan structure which comprises an outer frame, a circuit board and blades. A through hole with the inner diameter at least equal to the length of the blade is formed in the outer frame, and a blocking piece is formed in the middle of the end face of one end of the outer frame. The circuit board and the blade are arranged in parallel and then are arranged in the through hole of the outer frame, and the circuit board is fixedly connected with the separation blade; a limiting groove is formed in the edge of the end face, provided with the blocking piece, of the outer frame, and the limiting groove is used for containing a connecting part of a connecting line of the circuit board. The automatic assembling device solves the problems that in the existing vehicle-mounted host fan assembling process, automatic assembling cannot be achieved through a mechanical arm, and in the
